Here are the 424B prospectus supplements from BlackRock Taxable Municipal Bond Trust (BBN) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow BBN and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full BBN filings page.
