EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to ε Aur. The system is characterized by grey and asymmetric eclipses every 5.6 yr, with a significant variation in their photometric depth, ranging from ~0m.5 to ~2m.0. Aims. The main aim of the observational campaign of the EE Cep eclipse in 2014 was to test the model of disk precession (Gałan et al. 2012). We expected that this eclipse would be one of the deepest with a depth of ~2m.0. Methods. We collected multicolor observations from almost 30 instruments located in Europe and North America. This photometric data covers 243 nights during and around the eclipse. We also analyse the low- and high- resolution spectra from several instruments. Results. The eclipse was shallow with a depth of 0m.71 in V-band. The multicolor photometry illustrates small color changes during the eclipse with a total amplitude of order ~ +0m.15 in B-I color index. The linear ephemeris for this system is updated by including new times of minima, measured from the three most recent eclipses at epochs E = 9, 10 and 11. New spectroscopic observations were acquired, covering orbital phases around the eclipse, which were not observed in the past and increased the data sample, filling some gaps and giving a better insight into the evolution of the H α and Na i spectral line profiles during the primary eclipse. Conclusions. The eclipse of EE Cep in 2014 was shallower than expected 0m.71 instead of ~2m.0. This means that our model of disk precession needs revision Description: We present a catalog of photometric and spectroscopic data collected during and around of EE Cep eclipses in 2014. The photometric data were obtained with 26 different instruments, mainly inJ ohnson and Johnson-Cousins UBVRI(RI)C bands, and some small sets of the data were obtained with interference filters JHK. The photometry from the eclipse have been compiled into the set of consistent photometric data in UBVRI(RI)C bands, that has been used in the paper. The spectra released in this catalog were obtained with 6 different spectrographs at low, medium and high resolutions (R in range ~500 -- 30000). The 10 of these spectra cover narrow ranges of order 200 Angstroms with H-alpha, H-beta lines or NaI dublet, and the rest of them cover longer ranges of wavelengths - several thousands of Angstroms in the visual domain or in the near infrared.
