In all honesty, textbooks, really good specialized stuff, is not online or if it is very difficult and too expensive to read online because the whole text is online...ie. 500-800 pages long with hypertext links all over the place. Creates fragmented understanding about mergers and acquisitions.

Research must be approached not only online, but many of the expensive texts that exist in your university library. If your university has a business faculty/business school, then it should have a significant library section or whole business library where there would be texts on U.S. and international mergers and acquisitions.

Research, if approached strategically needs to consider key databases ...and STILL whole world of print materials is current and easier to grasp more quickly, and sometimes only published in hard copy, in electronic form.

Searching the database of your university library from the comfort of your home.. before dropping by. If you paid an annual membership to use the university library, it is possible then you might be granted access to a wider range of fee-based/licensed research databases ..like a fee-paying student or faculty member would have just benefits.

Securities Exchange Commission (SEC) of course has your official documents that track the completed filings for mergers...and demergers for publicly listed companies that trade in the U.S. Canada has SEDAR, a publicly accessible national database..which would include Canadian and U.S. firms that trade on the Canadian stock exchange, TSX.

I am aware that some Canadian librarians take several courses to be certified with the Canadian Securities Institute, learn about financial instruments, terminology, etc. TLere are exams. But it is to my understanding worthwhile for them, to conduct complex searches that require understanding the terminology to zero in on the right results.

Or perhaps your university business library offers a 1 hr. course how to do more effective research. Never hurts to ask..

If a public library has an extensive floor/whole department devoted to reference and research on business resources, they miught also offer some expertise to show you certain things.

Yes, being librarian is more than the glasses and hairbun (of which I don't sport)..it has been a great journey so far.. and technology just adds on top of what we need to remember and update our brains.
