Search 5 online libary catalogs at once

[AgedTea]

I would like to search five libraries at one time. Is there a way I could create a simple webpage or whatnot so that I could type in my search word once and then have five different libraries' search engines running at the same time with the same search word?

They are in this sort of syntax:
https://www.LibraryA.com/search?query=%s
https://www.LibraryB.com/search?query=%s
https://www.LibraryC.com/search?query=%s
https://www.LibraryD.com/search?query=%s
https://www.LibraryE.com/search?query=%s
where ”%s” is all the same keyword/phrase.


I use Firefox and have created a keyboard shortcut for each. For example, "libraryA foo". But that means I have to also do "libraryB foo" and "libraryC foo" and "libraryC foo" and so on.

Please help. thanks.
