ProQuest Dissertations & Theses (PQDT) provides a very comprehensive collection of dissertations and theses and is the official digital dissertations archive for the Library of Congress. The database provides full text for most dissertations after 1997, and older materials that have not been digitized are available for purchase as printed copies.
This compares the same search in 3 different article databases, in this case a search for François Englert, one of the Nobel Prizewinners in Physics, in order to give you some ideas about the differences between the databases' coverage. Englert works primarily in theoretical particle physics, and he will show more literature results in databases containing more information from that subfield. (For a list of databases to use for searching, see the left-hand column!)
Each of these searches returns different results based on the following:
INSPIRE has recently had a major interface redesign, with divisions between different types of searches. The main literature search is the default when you visit the citation database. If you click on the author tab (shown), you can type in the name of a physicist to see how many publications are in the database. Englert has 121.
Note that, if you wanted to do a free search for people with his last name and first initial, you could do an author search using the instructions on the main search page.
Steps before the screen shot: I searched the Core Collection (not All Databases) for englert f* — the * being a wild card that will find all matches, regardless of whether he used his first initial or not. I added a field that would search Organization-Enhanced for the Université Libre de Bruxelles.
The search returned 74 results, including Englert's Nobel lecture.
Unfortunately, I cannot share searches from the Web of Science, but you can easily recreate it. One of the reasons why the results are so low is that the Web of Science relies on author information submitted in the papers. It is possible to locate additional papers in the Web of Science for a researcher if you know what you are looking for.
Steps before the screen shot: I used the advanced search to do an author search for englert, f*. From the search, I clicked on the name of the correct Englert, which elimnated one search result — there is an early-career researcher in Physics who shares Englert's name, but with a middle initial.
The outcome of the search is here: 35 results.
But why so few, if arXiv is the primary Physics preprint server? arXiv came online in the 1990s, decades after Englert started publishing. Many preprints will not be in the arXiv beacuse the workflow at the time did not include arXiv dissemination.
