Dictionaries from Leeuwenhoek's time

The two major Dutch-English dictionaries of the time bracket Leeuwenhoek's career.

In 1648, Hendrick Hexham (1585?–1650?), an ex-soldier, published Het Groot Woordenboeck, the first Dutch-English / English-Dutch dictionary, including a grammar. The English-Dutch part was published in 1648 and the Dutch-English part in 1658, both in Rotterdam by Arnout Leers.

The DBNL (Digitale Bibliotheek voor de Nederlandse Letteren \ Digital Library of Dutch Language and Literature) has made a downloadable and searchable PDF of the 1675 edition, amended and enlarged by Daniel Manley, available at Google Docs. A version is available for download at Google Books.

In 1691, A large Dictionary English and Dutch, written by Willem Sewel (1654–1720), was published in Amsterdam by Steven Swart. The third edition from 1735 is available at Archive.org as well as Google Books.
 
The Instituut voor Nederlandse Lexicologie (Dutch Institute for Lexicology) has a terrific online service (logo below): Historische woordenboeken op internet (Historical dictionaries on the Internet). It searches the Woordenboek der Nederlandsche Taal (Dictionary of the Dutch Language), among others.

Dictionaries Today

Van Dale's is the standard Dutch-English dictionary (two blue volumes below). It is especially strong on usage of the terms in phrases that help distinguish the subtle but important differences. I use the version (below right) you can download to your computer. If you enter a verb form, it shows you correct infinitive.

Grammar

Donaldson's Dutch grammar (red cover below) is the best I have found written in English.

Donaldson, Bruce. Dutch: A Comprehensive Grammar (paperback | hardback). New York: Routledge, 2008

The best online grammar site I've found is DutchGrammar.com, which has a grammar reference, also downloadable, audio files to help with pronunciation, and a forum where many nuances get explained.

Verbix's Verb conjugation on-line - Dutch - is helpful for writing.
