One of the oldest sources which covers most of Bohemia is the Serfs register according to their faith (soupis poddaných podle víry) which was created in 1651. It covers just Bohemia, not Moravia or Silesia. If your ancestors were from Bohemia, it is a wonderful source of information.
The register was created shortly after the Thirty Years' War and it was a basis for the recatholization of Czech lands. Most of the serfs were of non-catholic, yet Christian views - they were Czech brothers, hussites, we can call them protestants or evangelicals. The aim of the register was to track those people and families who were non-catholic - and persuade them (or force them) to become catholic. To be sure no one was missed the register was created.
The register was created for all of the Bohemian regions. These regions were usually called after their "capitals" - Bechyně, Beroun, Chrudim, Čáslav, Hradec Králové/Nový Bydžov, Kouřim, Litoměřice, Loket, Mladá Boleslav, Plzeň/Klatovy, Prácheň, Rakovník, Slaný, Vltava (after river Vltava) and Žatec. The register was unfortunately destroyed for four regions - Litoměřice, Prácheň, Slaný and Vltava region.

National Archives in Prague published the registers for those regions which still exist as books. And as it was almost impossible to buy these book, National Archives decided to publish a digital version of these books and make them available for anyone who is interested. They published them on their website: https://www.nacr.cz/vyzkum-publikace-odborne-akce/publikace/e-knihy. As it is a bit complicated to download the PDF files, here are two screenshots from the website (first click on Detail and then on E-kniha ke stažení zde):
And what can you find in these books? There are lists of serfs divided by the estate and the town they lived in. Here is an example of a small village called Votice (today Otice) on Uhříněves domain, Kouřim region, south from Říčany.

The register shows following information:
First column contains name (and surname, if available, if not, just N. is showed), second column informed if the person is serf of the domain (p for poddaný, ie. serf, np as nepoddaný, ie. not serfs of that domain), third column contains occupation or social status of the person (see list below), fourth column contains age of the person, fifth and sixth column contains information about the religion (k for katolický, catholic, n for nekatolický, non-catholic). The last column, containing +, means there is a chance to convert the person to the catholic religion.
The most common occupations or social status of the people listed in the register:
