Comptes Rendus de l'Académie Bulgare des Sciences: Scopus, Scope & Submission Guide
Comptes Rendus de l'Académie Bulgare des Sciences, also presented in English as Proceedings of the Bulgarian Academy of Sciences, is a long-running multidisciplinary scientific journal of the Bulgarian Academy of Sciences. The supplied source record identifies it as a Scopus journal with Source ID 31728 and print ISSN 1310-1331. The official journal site additionally lists online ISSN 2367-5535, the ISO abbreviation C. R. Acad. Bulg. Sci., and a founding year of 1948.
The journal is unusual in breadth but strict in format. It publishes peer-reviewed short reports of original, unpublished scientific results across astronomy, mathematics, physics, chemistry, biology, geology, geophysics, space sciences, engineering sciences, physical geography, medicine and agricultural sciences. The current instructions emphasise concise reporting: a normal manuscript should be in English, should not be descriptive or polemical, and should remain within eight standard typewritten pages or 16,000 characters, including figures and tables.
For researchers considering this title for a PhD publication, research output or institutional requirement, the central question is not simply whether the journal is indexed. Authors should assess whether the study can be communicated as a short original report, whether its discipline matches the journal's active sections, whether the required manuscript compression can be achieved without weakening methodological transparency, and whether the latest indexing, quartile and fee information meets the rules of the author's institution.
Quick Answer: What Is Comptes Rendus de l'Académie Bulgare des Sciences?
Comptes Rendus de l'Académie Bulgare des Sciences is the Proceedings journal of the Bulgarian Academy of Sciences, founded in 1948 and published from Sofia, Bulgaria. It is multidisciplinary rather than confined to a single field. The journal's own pages list sciences ranging from mathematics and physics to biology, medicine, engineering and agriculture, and its 2026 issues continue to publish across several of those sections.
The source supplied with this task identifies the journal in Scopus under Source ID 31728. The journal's official site states that manuscripts undergo peer review and copy editing. Standard papers are short reports of original scientific results; Concise Review Papers are also published, but the instructions describe those reviews as invited by the Editorial Board.
Before submission, authors should verify the current Scopus source profile, institutional quartile requirements, the latest author instructions and publication fee rules. Metrics and database classifications change over time, and the journal's older website still displays historical metric values that should not be mistaken for current 2026 values.

Methodology and Sources
This profile was prepared by matching the supplied Scopus source identifiers with the journal's official website, current Instructions to Authors, submissions page, editorial-team page, current 2026 issue archive and ISSN Portal records. Older journal pages were used only for historical context, particularly where they display dated citation metrics.
Journal information is time-sensitive. Indexing coverage, metrics, fees, editorial roles and submission routes can change. For a high-stakes university or promotion requirement, researchers should recheck the current Scopus source page, the official author instructions and any institutional journal-list rules immediately before submission.
Aims, Scope and the Type of Research the Journal Publishes
The journal's stated purpose is concise dissemination of original scientific results. Its official instructions describe peer-reviewed short reports in astronomy, mathematics, physics, chemistry, biology, geology, geophysics, space sciences, engineering sciences, physical geography, medicine and agricultural sciences. The instructions explicitly reject papers that are merely descriptive or polemical and require unpublished results.
This makes the journal broad in discipline but narrower in article function. A manuscript may fit thematically while still being unsuitable if it needs extensive background, a long methodological exposition, many figures or a large reference list. The publication model favours a compact scientific contribution that can communicate its problem, method, result and significance within a strict space constraint.
Evidence from current issues
The July 2026 issue includes work in mathematics, chemistry, biology, geophysics, engineering sciences, medicine and agricultural sciences. Topics range from nanofiltration and laser-induced spectroscopy to wind-power forecasting, deep-learning environmental monitoring, Helicobacter pylori genetics, mesenchymal stem cells, wheat genotypes and climate-linked fruit biochemistry. This supports the journal's current multidisciplinary character rather than treating its scope as a historical statement only.
Who may find the scope appropriate?
Researchers with a focused result that can be reported concisely may find the format appropriate, particularly when the work sits clearly within one of the journal's named sections. Interdisciplinary work can also be plausible where the central contribution is recognisable to one of those sections. Authors should inspect several recent papers in the relevant section to compare methodological density, article length, figure use and level of discussion before deciding that broad subject overlap is sufficient.
Article Types and Manuscript Fit
The normal submission is a short report of original scientific results. The current instructions also mention Concise Review Papers, described as short surveys reflecting recent achievements in a field, but these are published at the invitation of the Editorial Board and may extend to 20 standard pages.
| Manuscript type | Fit assessment |
|---|---|
| Focused original research result | Potentially strong fit if novel, within scope and compressible to the journal's short-report format. |
| Large full-length empirical paper | May be difficult to fit if essential methods, data, figures or interpretation cannot be communicated within the strict limit. |
| Purely descriptive survey | Potentially unsuitable because the instructions say papers should not be descriptive or polemical. |
| Concise review | Possible by invitation of the Editorial Board; do not assume unsolicited reviews are accepted. |
| Preliminary concise communication | The journal states that reported results may later be expanded for publication elsewhere, but authors must still avoid duplicate publication and follow both journals' policies. |
Scopus Indexing, Metrics and Quartile: What Authors Should Verify
The supplied dataset identifies the journal as Scopus Source ID 31728, which is the correct identifier to use when checking the source. This is more reliable for disambiguation than searching only by title because the journal has parallel English, French-transliterated and Bulgarian titles.
The official older journal site displays historical values such as a 2020 CiteScore of 0.90, SJR of 0.244, SNIP of 0.353 and a 2020 Impact Factor of 0.378. These values are useful only as historical records. They must not be presented as current 2026 metrics.
A TU Dresden institutional research portal labels the journal's 2024 Scopus rating as CiteScore 0.6, SJR 0.154 and SNIP 0.277. Because this is an institutional secondary presentation of Scopus data rather than the directly accessible Scopus source profile, authors should verify the latest reporting year directly in Scopus before citing the figures in an academic application or journal-selection document.
Quartile caution: quartiles depend on year and subject category. A statement such as “the journal is Q3” without year, category and database can be misleading. If your PhD regulation specifies “Scopus Q1/Q2” or a particular JCR category, check the exact current database record used by your university.
Preparing and Submitting a Manuscript
Core length and language requirements
The current official instructions require manuscripts in English and limit normal papers to eight standard typewritten pages or 16,000 characters, including figures and tables. No more than four figures and tables are allowed in total. Spelling should follow the preferred spelling of the Shorter Oxford English Dictionary.
Initial submission package
The detailed author instructions state that the manuscript text, abstract, keywords, figures and tables should be sent as a single PDF to the editorial office, together with a cover letter providing the corresponding author's name, address and telephone number. Mathematics papers must include Mathematics Subject Classification (MSC 2020) information.
The journal's OJS Submissions page also displays a login/register submission interface and a checklist. Because the official pages show both an OJS workflow and email-based detailed instructions, authors should verify the currently preferred submission route before sending files rather than assuming one route supersedes the other.
After approval
After approval, the corresponding author is asked to provide the article in Word or LaTeX, separate table files, separate figure files and a file containing figure captions and table text. The instructions specify 11-point Times New Roman for Word, or standard Computer Modern fonts for LaTeX, and state that Word files are converted to LaTeX for typesetting. The journal also specifies SI units, a decimal point, image-resolution and file-format requirements, and CMYK handling for colour graphics.
References, Author Details and Proofs
References are limited to up to 20 cited works and arranged in the order in which they appear. In-text references use the corresponding number in square brackets. For journal references, the instructions specify surname and initials, year, article title, ISO4 journal abbreviation, volume, issue and cited pages. Where there are more than three authors, the reference lists the first three followed by et al.
Each author's full address, including postal code and email address, should appear after the references. The current instructions also request ORCID and/or Scopus ID information for the corresponding author and for other authors who have those registrations. Authors are offered one proofreading, with corrections mainly limited to errors introduced during preparation for printing.
Peer Review, Editorial Screening and Editorial Leadership
The official About page states that all manuscripts are subject to peer review and copy editing. The public information reviewed for this guide does not specify a current acceptance rate or an official average number of days to first decision, review or publication. Those figures should therefore not be estimated.
The current Editorial Team page lists Vesselin Drensky of the Bulgarian Academy of Sciences as Editor-in-Chief and provides an editorial board plus an international editorial council. For a multidisciplinary journal, this structure is relevant because submissions span very different scientific domains.
As a practical publication-readiness step, authors should expect an initial scope and format check before specialist review, even though the exact internal sequence and timing are not fully detailed publicly. A manuscript that exceeds the length limit, uses too many figures, lacks an original result or falls outside the named disciplinary areas risks difficulty before the scientific merits can be fully assessed.
Publication Fees, Access and Copyright
The official author page states that the journal is funded by the Budget of the Republic of Bulgaria and provides differentiated publication-fee rules. For papers submitted after 1 January 2026, foreign authors owe 300 euros. Bulgarian authors with project funding pay 300 euros, while those without such funding are exempt. For a mixed Bulgarian/foreign team, the foreign co-author share is 150 euros; the Bulgarian side pays the other 150 euros if it has funding and is exempt if it does not.
Authors should confirm the latest fee page before payment because the same page also preserves earlier fee rules for older submission dates. The journal provides downloadable full-text articles on its website, while its Copyright Transfer Agreement states that each author must sign a transfer after acceptance. Free reader access should therefore not be assumed to mean a Creative Commons licence or author-retained copyright.
How to Decide Whether This Journal Fits Your Manuscript
- Match the discipline: locate your study within one of the journal's named scientific sections.
- Test the short-report format: determine whether the complete scientific claim can be responsibly communicated within eight pages/16,000 characters and the four-figure/table ceiling.
- Check originality: the journal requires unpublished results and says papers should not be merely descriptive or polemical.
- Compare recent papers: inspect current issues in your section for typical methods, evidence density, result framing and reference patterns.
- Verify indexing for your purpose: confirm Source ID 31728 in Scopus and the current quartile/category if your institution uses a ranking threshold.
- Check logistics: review the current submission route, fee status, copyright agreement and the requirement concerning submission for printing by a member of the Bulgarian Academy of Sciences after acceptance.
A manuscript can be scientifically strong and still be a poor fit if it needs a conventional long-form article structure. Conversely, a focused result with a clear contribution and disciplined presentation may align well with the journal's communication model.
Common Reasons a Manuscript May Be Unsuitable
- The topic does not clearly belong to one of the journal's scientific subject areas.
- The work is descriptive without a sufficiently original scientific result.
- The manuscript is too long to preserve methodological and evidential integrity under the journal's short format.
- More than four figures/tables are essential to understand the study.
- The reference base cannot reasonably be reduced to the journal's maximum of 20 cited works.
- The paper has already been published or is simultaneously under consideration elsewhere without an allowable explanation.
- The manuscript is a review submitted without evidence that it is invited.
- The author relies on an old metric or quartile without checking the current database record required by the institution.
Publication-Readiness Checklist
| Check | Ready when... |
|---|---|
| Scope | The central research question clearly fits a named journal discipline and resembles the level of recent section content. |
| Novelty | The paper communicates an original, unpublished scientific result rather than a descriptive summary. |
| Length | The complete paper can meet the 8-page/16,000-character limit without omitting essential evidence. |
| Visuals | Figures and tables together do not exceed four for the standard report. |
| References | No more than 20 references are used, in numbered order-of-appearance style. |
| Identifiers | Author addresses, emails and applicable ORCID/Scopus IDs are prepared. |
| Files | Initial PDF and cover-letter materials are ready, with post-approval Word/LaTeX and separate artwork files planned. |
| Institutional requirement | The current Scopus coverage and any quartile requirement have been checked in the required database. |
