Answers use saved listing facts and recorded sources.

What it does

Google Books provides search across an index of book texts with a library area and publisher information.

Search a phrase or subject when you want to locate it in books rather than general web pages. A book-index result is a discovery lead, so inspect the specific record before deciding what reading access it offers. Keep author and edition details when carrying a result into a bibliography.

Evidence

Separate website checks

These checks do not add points to the SI Score. They inspect the website's HTML, not the product in use.

How the SI Score works →

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.

Sources and checks

Supporting pages for product usefulness, site facts, prices and separate website checks. Each record keeps its own date. Reading a page does not establish how well the product performs in use.
