One of the most frequent mistakes that occur is the use of diverse citation managers and tools to create bibliographic citations. According to ISO 690, for example, each individual citation is OK, but all of them cannot be used in a single list.
NOT LIKE THIS
An example of correct citations that cannot be used in one bibliography because each one
of them is created differently:

A mistake can also include disharmony between the in-text referencing and the list of citations:
The Harvard method of referencing (name, date) very often appears in the text of the thesis, but in the list of bibliographic citations the year of publication of the work is not placed immediately after the author, which is what the whole style (system) is based on.
It is, therefore, necessary to follow a uniform citation style both in the in-text referencing and in the list of used literature.
Another relatively frequent mistake is to omit the space after the punctuation mark or to use a hyphen instead of a dash in the extent (e.g. of pages or years):
ŠIMETKA,Ondřej. Zmenšující (destruktivní) operace. Moderní gynekologie a porodnictví,2009,roč.18,č. 3, s.285-289. ISSN:1211-1058.
Conversely, in the titles with secondary titles, there is often an erroneous space placed on either side of the colon. It is usually created by copying from the library catalog.
PROŠKOVÁ, Eva. Mýty a skutečnost specializované způsobilosti všeobecných sester. Florence : časopis moderního ošetřovatelství, 2010, 6(6), 3–4. ISSN 1801-464X.
It is also a frequent mistake not to give the exact date for sources that require this: online sources, patents, radio or television broadcasts (time is also stated here). Especially in the Harvard style, where the year of publication is given right after the author. The more precise date must then be given in the usual place.
