In this work, we present digital and graphical atlases of spectra of both thesolar disk-center and of the limb near the Solar poles using data taken at theUTS-IAP & RIAAM (the University of Tabriz Siderostat, telescope andspectrograph jointly developed with the Institut d'Astrophysique de Paris andResearch Institute for Astronomy and Astrophysics of Maragha). High resolutionand high signal-to-noise ratio (SNR)CCD-slit spectra of the sun for 2 differentparts of the disk, namely for $\mu$~=~1.0 (solar center) \& for $\mu$~=~ 0.3solar limb) are provided and discussed. While there are several spectralatlases of the solar disk-center, this is the first spectral atlas everproduced for the solar limb at this spectral range. The resolution of thespectra is about \emph{R}~$\sim$~70 000 ($\Delta\lambda$~$\sim$~0.09 {\AA} withthe signal-to-noise ratio (SNR) of 400$-$600. The full atlas covers the 3980 to7100 {\AA} spectral regions and contains 44 pages with three partial spectra ofthe solar spectrum put on each page to make it compact. The difference spectrumof the normalized solar disk-center and the solar limb is also included in thegraphic presentation of the atlas to show the difference of line profiles,including far wings. The identification of the most significant solar lines isincluded in the graphic presentation of the atlas. Telluric lines are producinga definite signature on the difference spectra which is easy to notice. At theend of this paper we present only two sample pages of the whole atlas while thegraphic presentation of the whole atlas along with its ASCII file can beaccessed via the ftp server of the CDS in Strasbourg via anonymous ftp tocdsarc.u-strasbg.fr (130.79.128.5) or via this link\footnote{\url{http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/other/ApSS}}.
