Find academic articles and ebooks: verify the work, version and access route

1. Identify the exact work

For articles record title, authors, year, journal and DOI where available. For books include edition and ISBN. Chapters and pagination can change between editions; cite the version actually read.

Compare metadata with the publisher or official record. Remove duplicated URL prefixes and trailing citation punctuation from copied DOIs rather than guessing an identifier from a similar paper. Check the reference list where you first encountered the work.

2. Search Scholar and library routes

Google Scholar offers full-text links, versions and configured library links (Google, n.d.). Start with a quoted title and add an author if needed. A side link may lead to an institutional repository rather than the journal.

In a hypothetical search exercise, copy the exact reference title, compare authors and year, inspect the publisher record and then check available versions. Try institutional library access when needed. This is a retrieval sequence, not a guarantee of free access.

Do not describe a search snippet as though you had read the article. If only the abstract is available, record that limitation and seek the full text for claims requiring methods or tables.

3. Match open-access services to their scope

Unpaywall locates indexed open versions associated with DOIs (Unpaywall, n.d.). No result does not establish that a paper is nonexistent or that no author-shared version exists.

PMC archives full text in biomedical and life-science fields (National Library of Medicine, n.d.). A PubMed bibliographic record does not automatically imply a PMC full-text copy.

DOAB helps discover scholarly open-access books subject to publishers’ peer-review processes (Directory of Open Access Books, n.d.). It is not a directory of every commercial book.

4. Distinguish manuscript versions

A preprint, accepted manuscript and version of record can differ in tables, supplements, pagination and conclusions. Read repository and file version information. A PDF layout or institutional logo alone cannot establish peer review.

When reading an accepted manuscript, compare publication metadata where available. If a claim depends on material that differs across versions, identify the version used. Cite a preprint as a preprint rather than inventing a journal record.

Check relevant methods, supplementary material and correction notices. A correct title with a missing supplement may still be insufficient for replication. Resolve author or DOI mismatches before using the file.

5. Decide what to do when full text is unavailable

Try the author’s website or institutional repository and library services, then consider asking the author for a permitted copy. Identify the work clearly; there is no need to disclose client data or your own manuscript to request reading access.

Record “full text not read” when access remains unavailable. A related accessible study can be useful, but it must independently support the claim. Do not silently substitute it while retaining conclusions attributed to the unavailable work.

For books, use authorized sample chapters, contents pages or library borrowing. A reposted download is not evidence of distribution permission. Public website links should favor original sources and clear access information.

6. Keep a retrieval and citation record

• Verify authors, title, year and edition.
• Match DOI/ISBN rather than guessing.
• Identify the version and sections actually read.
• Inspect relevant supplements and updates.
• Keep source URLs and applicable access/license details.
• Support claims with material actually examined.

The result should be the correct work and a clear route back to it, not merely a folder of similarly named files.
