The thesis analyses etymological information in electronic lexicographical publications as compared with printed ones. An overview of recent studies in this field is followed by an outline of the data set for analysis. The analysis is conducted on the basis of four domestic and foreign lexicographical publications - a printed etymological dictionary of English, a digital etymological dictionary of Turkish and digital non-etymological dictionaries of Croatian and English. The thesis examines the approach towards etymological information through analysis of loanwords and inherited words in terms of extensiveness, i. e. brevity of etymological information. The approach towards etymological processing of compound words is also analysed. The thesis examines whether the morphological analysis of etymon is included in the etymological part of the dictionary entry and provides an overview of the difficulties associated with the dictionary structure. The research shows that the depth of analysis varies among dictionaries, so sometimes different etyma are given for the same word. Furthermore, morphological analysis of etymon is present only in the digital etymological dictionary. While the digital non-etymological dictionary of the Croatian language etymologically described borrowed words more succinctly than inherited words, other dictionaries retained the same approach to the processing of both types of entries. The research also confirmed that the problem of referring to other entries is most present in the printed dictionary, while in electronic editions this shortcoming was solved by using links.
