Data The data described here were retrieved from multiple bibliographic databases. Due to

license terms the database raw data cannot be provided for download. Data were aggregated,

normalized and analyzed with help of a Python script (https://github.com/tuub/oa-eval, code

documentation in English). Search queries and download settings for these databases are doc-

umented in the (German) manual that accompanies the script. For a detailed description of the

retrieval process and the analysis steps see the report. Data are distributed under the Creative

1 General remarks

The overall goal was to analyze the publication output from nine research institutions located

in Berlin (Germany) and determine the share of open access journal articles. Journal articles

whose authors are affiliated with the following nine institutions were analyzed:

•Alice Salomon Hochschule (ASH Berlin)

•Beuth Hochschule für Technik Berlin (Beuth)

•Charité – Universitätsmedizin Berlin (Charité)

•Freie Universität Berlin (FU Berlin)

•Hochschule für Technik und Wirtschaft Berlin (HTW Berlin)

•Hochschule für Wirtschaft und Recht Berlin (HWR Berlin)

•Humboldt-Universität zu Berlin (HU Berlin)

•Technische Universität Berlin (TU Berlin)

•Universität der Künste (UdK Berlin)

Data were retrieved from sixteen bibliographic databases: Academic Search Ultimate (EBSCO),

Business Source Complete (via EBSCOhost), CAB Abstracts (via OvidSP), CINAHL (via EBSCO-

host), Embase (via OvidSP), IEEE Xplore, Inspec, Library and Information Science Abstracts

(LISA) (via ProQuest), ProQuest Social Sciences, GeoRef (via ProQuest), PubMed, SciFinder (CA

Plus), Scopus, Sport Discus (via EBSCOhost), TEMA and Web of Science Core Collection.

To identify articles in gold open access journals1the Directory of Open Access Journals (DOAJ)

was used.2In order to reduce script run time the API3provided by DOAJ was not used. Instead,

DOAJ data were downloaded as comma-separated file4. The csv file was saved as tab-delimited

file; the file doaj.txt constitutes the state of DOAJ metadata as of October 28th, 2020 – listing

15.413 open access journals. An article is considered to be gold OA if the journal is published

in DOAJ.

To identify open access articles in hybrid journals5a combination of data retrieved from the

UnpaywallAPI6andthe CrossrefAPI7wasused(November2020). Unpaywalldatawerechecked

for OA status, host type (publisher or repository) for the detected OA version and license in-

1An open access journal publishes open access articles, i. e. all published articles are openly available on the

publisher’s website, without charge or delay.

2The analysis does not rely on Unpaywall data ‘Unpaywall[journal_is_oa]’) for detection of Gold OA articles

because 1) it would leave articles without a DOI undetected and 2) samples showed that Unpaywall data are

incomplete on journal OA status.

4DOAJ metadata: CSV file https://doaj.org/csv

5A hybrid (open access) journal publishes both closed access and open access articles. It is operated under a

subscription business model with the (fee-based) option to make single articles open access.

formation; Crossref data were checked for license information. An article is considered to be

hybrid OA if a Creative Commons licensed version is accessible via the publisher website.

To identify green open access articles data from Unpaywall were used. An article is considered

to be green OA if the article is detected as neither gold OA nor hybrid OA and Unpaywall

detected at least one OA version in a repository.

Tab. 1 shows which values were included to determine the open access status.

Table 1: Detection of OA status

OA status Note

Gold OA DOAJ data as of October 28th, 2020 (ISSN + year lookup)

Hybrid OA according to Unpaywall (as of November 9th, 2020) and Crossref data (as of

November 12th, 2020)

following values must apply:

‘Unpaywall[is_oa]’ = TRUE,

‘Unpaywall[host_type]’ = ‘publisher’,

‘license’ = ‘CC*’

‘OA status’ != gold,

‘license’ = ‘CC*’

Green OA according to Unpaywall data as of November 9th, 2020

entries in ‘Unpaywall[OA Repos]’ were searched manually for ‘.com’; if

Unpaywall incorrectly assigned the ‘host_type’ = ‘repository’, the re-

spective entry was corrected (changed to ‘OA status’ = closed)

following values must apply:

‘OA status’ != gold OR hybrid,

‘Unpaywall[is_oa]’ = TRUE,

at least one entry in ‘Unpaywall[OA Repos]’

Data on APC costs for open access journals were retrieved from DOAJ (as of October 28th, 2020);

the costs were not verified manually. Since value-added taxes vary by country publishers usu-

ally list costs excluding VAT. APC listed here do not include VAT.

To determine exchange rates we consulted http://www.xe.com: Exchange rates were retrieved

forthebeginningof2019(January1st, 2019)andthecurrentrateatthedateofanalysis(Novem-

ber 11th, 2020).

2 Bibliographic data

Data were analyzed with regard to the following questions:

•How many journal articles did Berlin-based researchers publish in 2019?

•How many of these articles were published in open access journals (gold OA)?

•How manyof these articles have a Berlin-based corresponding author, in other words for

how many articles did a Berlin-based author (resp. his/her institution) most likely cover

the open access fee (Article Processing Charge, APC)?

•How many open access articles did researchers from Berlin publish in hybrid journals

(hybrid OA)?

•How many articles from Berlin-based researchers are available via a repository as green

open access (green OA)?
