The ACM Digital Library does not offer any sort of built-in screen reader. However, the ACM does list the following features for visual impaired users:
All text on the platform meets the minimum recommended contrast ratios against the background. This is 4.5:1 for normal text and 3:1 for large text. If you have trouble reading the text on the site you can change the text size as per the instructions given previously. Alternatively, you may find it helpful to use a browser extension to specify your own color combinations, such as Change Colors for Chrome browser.
Navigational images and icons, as well as many images in the content itself, contain useful alternative text. When alt text and long descriptions are available in the content, these are rendered in the interface.
The ACM Digital Library is designed to follow a logical reading order and semantic structure.
All content on the ACM Digital Library can be copied and pasted into a text-to-speech tool.
Further information can be found on the ACM's accessibility page.
The author of this guide tested several PDFs downloaded from ACM and found that they did not work properly with Adobe Acrobat's read-aloud feature. Alternatively, users should consider using the HTML version, as it should behave more consistently with screen readers.
Full-text articles in EBSCO databases may be available as either PDFs or as in-browser HTML documents.
All PDFs uploaded to EBSCO databases since September 2004 contain an Optical Character Reader (OCR) layer and are ADA-compliant. Unfortunately, PDFs uploaded prior to September 2004 are not ADA-compliant and cannot be read by a screen reader.
Compatible PDFs can be read aloud in Adobe Reader or Adobe Acrobat using the instructions found on the PDF Read Aloud page.
Articles available in HTML Full Text format can be read aloud by selecting the "Listen" option at the beginning of the article:
After selecting "Listen," the tool will display playback options:
Please see the EBSCO HTML Text-to-Speech instructions for further details.
HTML Full Text articles can also be downloaded in MP3 format.

Elsevier databases do not include a built-in read-aloud feature. However, some (though not all) PDFs tested by this guide's author seem to work properly with the read-aloud feature in Adobe Acrobat.

Elsevier databases include:
Listen feature
Most Gale databases include a Listen feature that can be accessed from the text's main listing page:
Selecting "Listen" will bring up a new panel that will allow you to start and stop the playback as well as change the volume.
Articles in Gale databases can also be downloaded as an MP3 file or as a PDF. However, Gale does not guarantee that downloaded PDFs will be ADA-compliant.
More details about accessibility in Gale/Cengage databases can be found on the Cengage Group Accessibility page.
JSTOR does not offer any built-in screen reader. However, the JSTOR accessibility page indicates that JSTOR should work well with browser plug-in tools such as Natural Reader.
JSTOR search results appear in the following order:
In order to utilize PDF screen readers, users can access full text articles as PDFs by choosing "Download" from either the results list or the article page. If a user discovers a PDF that has not been sufficiently tagged for screen readers, they can contact JSTOR and ask for the PDF to be manually tagged.
Project MUSE features several accessibility options, including high contrast and dark modes, which can be toggled in the Project Muse User Settings.
Unfortunately, Project MUSE's PDFs are not accessible and do not work at all with Adobe Acrobat's screen reader. However, users can also select View HTML in order to format the document with heading levels that will aid navigation.
Some ProQuest-published databases offer a built-in screen reader. Users can start the screen reader by selecting the "Listen" option located at the beginning of the article's full text:
Selecting this option will generate a widget that will allow the user to stop and start playback as well as change the volume and speed:
Most ProQuest databases also allow users to download full text documents as PDFs.
Further ProQuest accessibility information can be found in the ProQuest Accessibility Directory.
PubMed primarily links to articles found in other databases and hosts only the abstracts directly on PubMed. That said, abstracts found on PubMed can be displayed in a text-only format that should be very easy for third-party screen readers to navigate.
More information about PubMed's accessibility options can be found at the PubMed Accessibility page.
Springer's databases do not feature a built-in screen reader. However, PDFs tested by the author of this guide did seem to work acceptably with the Adobe Read Aloud feature.
Also, Springer notes that their website is compatible with modern screen readers, screen magnifiers, speech recognition software, and speech packages, but does not provide specifics. More information can be found on the Springer accessibility page.
Listing links on the SpringerLink results page will result in links being ordered according to date. Each subsection will list references from a specific time frame in the past, such as within the last two weeks.
Wiley's databases do not feature a built-in screen reader, and unfortunately, PDFs tested by the author of this guide were not consistently formatted properly for usage with the Adobe Read Aloud feature.
